Built for students and professionals in medicine, nursing, pharmacy, dentistry and allied health, DoctorAI helps you understand difficult topics, compare related conditions and turn your own study materials into questions. HOW IT WORKS 1. Ask – type, speak or scan a page. 2. Understand – read an answer organised with key points, tables and sources. 3. Keep it – highlight what matters, add notes and find everything again later. ASK YOUR WAY Type a question, record it by voice when that is quicker, or scan a page from your lecture notes or textbook. Short questions, long questions and follow-ups all work in the same conversation. CLEAR, STRUCTURED ANSWERS Answers are organised to be easy to read at a glance: headings, key points, comparison tables and step-by-step explanations. Research sources are listed under answers so you can read further. SIMPLIFY OR GO DEEPER Too complex? Turn an answer into a simpler version. Need more? Add extra depth to the same topic and keep both versions in your conversation. SCAN TEXT FROM YOUR STUDY MATERIALS Point your camera at a page, or choose a photo or file. Review and edit the extracted text, preview tables, then use it in your question. HIGHLIGHTS AND NOTES Mark important sentences and tables, add your own notes, and open them all in one place: Notes & Highlights.
